Study advances in modeling for polyolefin particle growth

Abstract

在聚烯烃生产过程中,聚烯烃颗粒粒径(大小及其分布)影响聚合速率、气力输送、后处理工序生产成本和最终的聚烯烃物性。为预测甚至调控生产过程中聚烯烃颗粒粒径,近期出现了许多烯烃聚合颗粒增长的模型化研究报道。本文简要介绍并比较了迄今所出现的主要聚合物颗粒增长模型,并指出如何用模型来描述聚合物颗粒增长情况。In the polyolefin preparation process,polymerization rate,fluid transport,and the cost of post-treatment after polymeric process and polymer properties may be affected by the polymer particle size and its distribution.In order to predict and control the polyolefin particle,many literatures report the models for polyolefin particle growth.In this paper,the main models on the particle growth are introduced and compared each other,while describing the mechanism of the polymer particle growth via model.中国石油化工股份有限公司福建炼油化工有限公司资助项目(G7808-06-ZS-1006
